APPLICATIONS
Thanks for purchasing your new White Brothers Fork. You
are in for the best ride of your life. Our forks are designed to
give you the level of performance you need to ride at your
absolute peak.
The White Brothers DH-2 fork features lightweight, dual
rate coil springs and an externally adjustable hydraulic
damper. This technology is borrowed from motorcycling and
offers the best possible suspension action. Steering accuracy
is improved over conventional MTB forks by utilizing dual
billet aluminum steering crowns, oversized 31.75mm fork
tubes, inverted stanchion/slider design and large 20mm axle.
Fork travel has been set at 6.10” (155mm) to offer the best
performance for downhill racing terrain. An optional 7.09”
(180mm) kit is available if longer travel is desired. A
combination coil spring and high-cushion bottom bumper is
used to minimize hard bottoming.
Every possible effort has been made to make the White
Brothers Fork very light in weight and perform at a level
superior to other forks on the market. To ensure peak
performance, proper installation and periodic maintenance is
required. Please read this manual in its entirety to familiarize
yourself with the fork to insure your satisfaction with this
product.
White Brothers Forks are designed for offroad use only.
They are not equipped with proper reflectors for road use. If
you are going to use your fork on the road, have your dealer
or mechanic install reflectors that meet the Consumer
Product Safety Commission’s (C.P.S.C.) requirements for
bicycle standards. If you have any questions concerning
C.P.S.C. Standards, please talk to your dealer.
When using your fork on public land and trails, please
respect the rights of other users and stay on established paths
and trails. By mountain biking responsibly, you help to
ensure the future of our sport.

FORK INSTALLATION
White Brothers DH-2 Fork features a 1 1/8” threadless steerer tube. If you have a threaded type fork on your bicycle, consult your
dealer for the appropriate upgrade parts necessary to convert to a 1 1/8” threadless steerer tube.
NOTE: Some frames are not adequately reinforced to handle loads applied by stiffer dual crown forks. Check with your frame
manufacturer to verify dual crown fork compatibility.
1.) Remove old fork from the bicycle. See your bicycle’s owner’s
manual. Measure the diameter and length of your old fork’s steerer
tube to insure that the White Brothers Fork steerer tube is the correct
diameter and has sufficient length for the installation. NOTE: Add
.65” (16mm) to length if you are upgrading from single crown fork
to dual crown model.
2.) Remove the crown race from your old fork. NOTE: Replace the
bearings if there are any signs of wear or corrosion
3.) Press the crown race onto the steerer of your White Brothers Fork
(figure 1).
4.) Preassemble headset by sliding fork steerer tube through headset
bearings. Then install top headset, top crown, stem spacer
(optional), and steering stem onto fork steerer tube. Refer to headset
owner’s manual if you have any questions about this preassembly
(figure 2).
5.) Read step 11 and check tire clearance prior to cutting steerer tube.
Mark steerer tube at top of steerer stem. Steerer must then be cut
3mm (1/8”) below this mark. Consult a dealer or mechanic if you do
not have the proper tools for cutting the steerer tube. NOTE: The
DH-2 fork will not work on frames with head tubes longer than 5
1/2”. NOTE (IF INSTALLING WB MX BAR MOUNTS):
Preassemble headset by: Sliding fork steerer tube through headset
bearings. Then install top headset, top crown and 5 to 10mm stem
spacer. Mark steerer tube at top of stem spacer. Steerer must then be
cut 3mm (1/8”) below this mark. Consult a dealer or mechanic if
you do not have the proper tools for cutting the steerer tu be.
6.) The special star fangled nut must now be installed into the
steerer. We recommend dealer installation of this nut since a special
tool is required.
7.) Clean and grease all headset bearings and races to prepare them
for assembly.
8.) Now assemble headset as done in Step 4.
9.) Install the top steering crown. Install the steering stem (threadless
type is required) and handlebars. Set your bars to your desired
height.
10.) Install the threadless mounting cap. Tighten the top threadless
stem bolt until there is no play in the fork tube. The fork should
rotate freely in the head tube. Secure the pinch bolts on the steering
stem. Consult the installation instructions for your threadless
bearing set to insure correct installation and tension of the headset .
11.) TIRE CLEARANCE: The fork tubes can be adjusted up or
down in the fork crowns to adjust ride height and steering geometry.
NOTE: At full extension of the fork, a minimum of 6 1/2” (165mm)
clearance must exist between tire and the bottom of the crown
(w/fork equipped with 6” travel internals). If fork has been modified
to 7” travel with WB option kit, a minimum 7 1/2” (190mm)
clearance must exist between tire and the bottom of the steering
crown. NOTE: DH-2 Fork
has approximately 3/4” negative travel. Pull up to fully top out
fork to make this measurement. WARNING: Any less clearance
than this will allow the tire to contact the bottom of the crown when
the fork is fully compressed. This could stop the wheel from
revolving throwing the rider and causing possible injury or death.
Next check to make sure the top of the fork tubes fit all the way
through the top steering crown. If insufficient clearance exists, you
must switch to a smaller diameter front tire. Tighten upper and
lower crown pinch bolts to secure fork legs into positio n.
12.) Install your front brakes and adjust following the manufacturers
specifications. See additional instructions below. NOTE: Only disc
type brakes can be used with the White Brothers DH-2 Fork.
13.) RIM CENTERING: See your dealer or professional wheel
builder to have the rim of your choice laced to your downhill hub.
The wheel builder will need to lace rim so that it is directly centered
between the fork legs, If you are using a 110mm hub you will need to
supply your wheel builder with the 10mm axle spacer (supplied) to
achieve correct wheel alignment.
14.) WHEEL/BRAKE INSTALLATION: The White Brothers DH2 Fork is designed for a downhill type hub utilizing a 20mm axle.
Install front wheel with disc rotor next to left side of fork. Slide axle
all the way through. Make sure disc rotor doesn’t contact left fork
axle seat when axle is tightened fully. If it does, a custom spacer will
have to be fabricated to space hub/rotor away at least 3mm from left
fork axle seat. At this time the brake caliper should be mounted and
alignment checked with the disc rotor. Follow the disc brake
manufacturers installation instructions to insure correct brake rotor,
brake caliper alignment.
15.) FINAL WHEEL INSTALLATION: Lightly grease front axle
and install front wheel to fork. Tighten axle completely. Now tighten
both left and right fork axle seat pinch bolts. Follow the disc brake
manufacturers installation instructions and recommended torque for
mounting brake caliper to left fork leg.
16.) Route hydraulic brake cable up to the brake lever. Make sure
that cable is routed so that it cannot foul on tire, fork crowns, or
steering stops through full up and down fork travel and side to side
steering radius.
17.) Check to see that your brakes are adjusted and working.
18.) STEERING CLEARANCE: Due to the White Brothers DH-2
double crown design, the fork tubes or fork steering crowns will
contact the bicycle frame at full steering lock to the left and right. To
eliminate the chance of damage to the fork or frame, a cushion stop
must be fabricated to eliminate metal to metal contact. Fork bumpers,
elastomers or thick pieces of rubber will work fine. Secure in place to
the frame or fork with zip tie or glue.

TUNING
*To get the most from your White Brothers fork, it is important that you tune the forks to fit your style of riding and the
conditions you ride in.
Initial break-in period
Your new fork is designed to break-in over a period of 10 hours or
more of riding. As all of the parts bed into each other, the stiction
(friction) of the fork will reduce and the fork will absorb the bumps
better. After this initial break-in, fine tuning the spring preload and
hydraulic damper may be beneficial to achieve the best possible fork
performance for your weight and riding style.
Tuning Your Springs
There are two ways to adjust your fork. The first is by changing the
changing the spring for a completely different rate. The spring
basically controls the quality of the ride. A stiff spring handles
major obstacles and dropoffs better, but doesn’t give as smooth of
ride over braking bumps and other small obstacles. Your White
Brothers Fork comes with a standard rate spring installed. For the
majority of riders, this should give a compliant ride, yet remain
resistant to bottoming. If forks are too stiff or too soft with the
spring supplied, WB offers an optional Soft (pn 97-3518) and
Heavy (pn 97-3508). Contact your WB dealer to order these. A fine
tuning adjustment for you fork is spring preload. As delivered, the
spring preload is correct for most riders. Spring preload is the
amount of pressure that the spring has against it at the full extended
position (spacers are used to adjust spring preload, see items #8 and
#10 on the exploded view page 8). With the correct preload on the
spring, with no load on the bike, the fork should come within 3/4” to
1” of returning to full extension after being compressed. Too much
sag, add (1) 2mm or 5mm spacer. Too little sag, remove (1) 2mm
spacer. Note: if your fork has an excess of stiction, complete basic
service first before preload adjustment.
Your White Brothers DH-2 fork comes with the damping adjusted in
the middle of its range. The standard setting is 3 turns out from all
the way in (clockwise). Use the following guidelines to determine if
further adjustment is needed.
A) If your fork rebounds too slowly, turn the adjustment screw on
the top of the right fork leg one turn counter-clockwise (8 turns out
is the maximum)(figure 3). The fork should absorb and return fast
enough to absorb the next major obstacle. A sign that your fork is
rebounding too slowly is if it feels like it pack-ups or continues to
compress as you go through rough sections.
B) If your fork is rebounding too fast, turn the adjustment screw on
the top of the right fork leg clockwise 1/2 turn at a time. A sign that
your fork is rebounding to quickly is if the fork deflects and the
bicycle is hard to hold in lines. The front wheel will also bounce
and appear “busy,” ie, you get an additional bounce after landing
from a drop. NOTE: If a stiffer spring is installed, your standard
setting should be 1 turn stiffer (clockwise). A light rider that has
installed a softer spring will usually be most satisfied with the
damping set at a lighter setting (4 to 6 turns out).
C) Tuning air pressure. The fork is set at 50psi. The minimum
air pressure is 50psi. At this setting the fork is very plush. To get a
stiffer feel, as well as faster rebound, add pressure up to a maximum
of 150psi. If rebound is too fast, turn damper adjuster clockwise.
Tuning Your Hydraulic Damper
Adjusting the hydraulic damper should only be done after you are
completely happy with your spring choice, and the proper spring
preload has been set.

MAINTENANCE
MAINTENANCE
Your White Brothers Fork requires periodic maintenance to insure peak performance and long life. Moisture and contamination may build up inside
the fork. We suggest you disassemble your fork, inspect, clean and re-grease them after 30 hours of use. If the fork appears to be relatively clean, you
can probably go 40 hours between servicing. If the fork appears dirty, you should service them every 20 hours. The three things that will most effect
the service interval and performance of your fork is water, mud and dust. How much time you use your fork in those conditions will determine how
much service it requires. NOTE: When cleaning the fork, it is not recommended to direct water spray at the seals. NOTE: Neglecting proper fork
maintenance will reduce the fork life. Internal build up of water and dirt, or a lack of lubrication will cause excessive wear to the fork. In harsh
conditions it is advisable to inspect the fork for dirt ingestion after each ride. Basic service should include disassembly of the fork, cleaning and regreasing all shafts and seals. At this time, the fork should be carefully inspected for wear and damage before reassembly. NOTE: Disassembly of the
hydraulic damper should be left for a dealer who is familiar with servicing the WB hydraulic damper and has the special tools that are required.
White Brothers recommends that you consult with a qualified technician before performing the following:
Basic Fork Disassembly
1.) Disconnect from brake caliper. Remove wheel assembly by loosening
fork axle seat pinch bolts and removing front axle.
2.) Loosen pinch bolts in steering crowns and slide each fork leg down
and out of steering crowns.
RIGHT FORK LEG (DAMPER SIDE) DISASSEMBLY
3.) Unthread top fork cap (counterclockwise) utilizing a 25mm (1") open
end wrench or adjustable wrench. If a better hold is needed, return leg
into crown, tighten and proceed to loosen cap (figure 4).
4.) Once top fork cap is loosened sufficiently that it is no longer attached
to fork stanchion, grasp lower fork leg at axle seat and compress fork
approximately 3". Loosen damper shaft from fork cap by securing the
shaft in aluminum clamp blocks pn 97-700 and turning counter clockwise
until cap can be removed from damper shaft (figure 5).
5.) Remove small collar from top of damper rod or inside cap. Remove
outer fork leg from inner leg (figure 6). NOTE: Have pan under fork to
catch small amount of oil that is in fork. No further disassembly is
required on right fork leg unless hydraulic damper is to be serviced.
HYDRAULIC DAMPER SERVICING
NOTE: Disassembly of the hydraulic damper should be left for a dealer
who is familiar with servicing the WB hydraulic damper. Special tools
are required along with experience in servicing hydraulic damper units.
6.) CAUTION: Damper oil is under pressure, directions for disassembly
must be followed very carefully. ALWAYS WEAR SAFETY
GLASSES AND PROTECT YOUR CLOTHES SHOULD OIL
SPRAY OUTWARDS. First, remove the core of Schrader valve.
NOTE: The failure of the piston o-ring will cause oil to squirt out of
Schrader valve. Cover valve core with a rag when removing. The core
should remain out until you reassemble the leg. Fold a thick cloth or
shop rag and then fold again to get 4 layers, place over the end on the
shaft. Next hold the rag tightly to the shaft and gently unscrew the needle
holding the end of the shaft down in a drain pan. This will release the oil
pressure in a controlled manner. Place leg in vise with soft jaws and
unscrew the seal head with a pin spanner. After all threads are showing
use a rag and pull up on seal head to expose the o-ring and remove from
leg. Grasp damper rod and lift up slowly. Remove nylon seal head and
complete damper rod assembly from fork leg. Dump old oil out of fork
leg. Remove damping adjust needle assembly from damping rod by
unthreading counter clockwise and pulling out of damping rod. Inspect
small o-ring on damping adjust needle assembly and replace if damaged
in any way. Also inspect o-ring on nylon seal head for swelling and
replace if damaged in any way. Also inspect damping piston ring to
ensure its sealing surface is smooth with no gouges or scratches. Replace
if necessary. If damper was leaking oil at seal head, replace this seal. It is
recommended that you always replace seal # WB-97-1409 every time
damper is disassembled. NOTE: Readjusting damper shim stack is not
recommended. If damping does not meet rider's requirements, call the
WB suspension service department for recommendations on valving
adjustments. Check the shims to make sure that they lay flat against the
piston. Carefully check that the rebound shim that is touching piston on all
sides. Replace if necessary. If shim stack is removed be extra careful not to
mix the shims. The shim on the shaft side must float on the aluminum
collar along with the spring.
FLOATING PISTON DISASSEMBLY
With schrader valve still out, remove floating piston with air pressure by
gently turning inner leg upside down, then place inner leg flat on a level
surface (table). Next, with a compressed air gun, gently introduce air into
the air valve. NOTE: Use eye protection with high-pressure discharge
operations. As pressure builds, the air valve piston will be forced out.
Now inspect piston for wear or damage. The o-ring should be replaced
every time the piston is removed.
REASSEMBLE DAMPER & FLOATING PISTON
7.) Apply non-lithium grease to groove of inner leg. Then install floating
piston by carefully easing it past the threads of inner leg. The hollow side
must face the air source or to the bottom of the leg. Continue piston down
into leg to a depth of eleven inches from top of tube. This depth is the
proper piston height in the leg. Next install schrader valve. Fill the leg to
the top with fork oil 3wt. to 5 wt. At this point insert the needle into the
shaft and screw in until the o-ring is just below the end of the shaft. Grease
the inner lip of seal head before installing on shaft. Install seal head with
new seal and o-ring on shaft; take care not to damage the small o-ring on
threads of the shaft. Install rod assembly with piston ring into leg. Use
your fingers to compress the piston ring taking care not to bind the ring.
The tabs should not overlap. Install in leg slowly. The shaft has a hole in it
that should face away from you. Cover it with your free hand. Oil will
squirt out when installing in leg. Push piston and rod under oil until the
hole in shaft is just under the oil level. Use one hand to keep shaft from
moving down any further and push the seal head into leg with your other
hand. Note the seal head has a hole in it; keep your hand over hole when
installing seal head. Keep pressure between the piston and the seal head
when screwing the seal head into the leg. DO NOT LET THE SHAFT
MOVE INTO LEG UNTIL THE LEG IS PRESSURIZED. If this
happens you will have to start over. Push seal head down past the o-ring
until the threads are touching top of leg. Let go of shaft and screw in the
seal head with a pin spanner. Fill the leg with 50-150 psi using a shock
pump. Now push the shaft down to see if it compresses and extends
smoothly. It should be in the fast return position. Now screw in the shaft to
see if the return slows down. If the shaft works in both directions the
FIGURE 4

assembly is complete. Adjust the setting after the cap is installed.
8.) At this point clean all parts with a clean, non-abrasive rag. A mild
grease cutting cleaner or solvent might make this an easier task.
9.) Once the legs are clean, inspect seals for tears or cracks. Next,
inspect the fork tubes for wear, nicks or scrapes. If there is noticeable
play between fork legs and fork tubes, the DU bushes located inside the
outer fork leg may require replacement. Consult White Brothers or your
dealer if servicing or repair is necessary. Special tools (available from
White Brothers) are required to replace and reinstall DU bushes.
10.) If everything is free of problems, coat all parts with a light coating
of suspension lube or other suitable, non-lithium grease. Also lube the
DU bushings that are located inside fork outer leg by dipping a socket
extension in grease and applying the grease to the DU bushings.
11.) If they are being replaced, install oil seals back into lip of outer leg,
then snap circlip into next lip, then wiper seal. Apply recommended
grease to seals. Carefully slide outer fork leg over inner fork leg making
sure not to curl seal lips (oil seal and wiper seal) under during this
process. Stroke outer fork leg to make sure it is sliding smoothly over
inner leg.
12.) Securing damper shaft with aluminum clamp blocks pn 97-700 in
vise, thread fork cap with small spacer in cap onto damper shaft
clockwise until fully tightened. Thread the fork cap into outer fork leg
and tighten fully. Stroke fork to check for smooth operation. Adjust
damping adjust needle to 3 turns out (counter clockwise) or the position
you have found to work best for you from past experience.
LEFT FORK LEG (SPRING SIDE) DISASSEMBLY
1.) Unthread top fork cap (counterclockwise) utilizing a 25mm (1") open
end wrench or adjustable wrench. If a better hold is needed, return leg
into crown, tighten crown, and proceed to loosen cap (figure 4).
2.) Once top fork cap is loosened sufficiently that it is no longer attached
to fork stanchion, grasp lower fork leg at axle seat and compress fork
approximately 1". Loosen dummy rod from fork cap by inserting 9/16"
wrench onto nut under fork cap and turn counter clockwise until cap can
be removed from dummy rod (figure 7).
3.) Remove 9/16" nut, alloy top spring collar, main spring and any nylon
spring spacers. Remove outer fork leg from inner leg. Spacers usually are
stuck in outer leg. Tap leg on workbench to remove them from threaded
end of outer leg. There can be 3-5 spacers in leg.
4.) To disassemble and inspect negative spring, secondary compression
spring and dummy shaft system, remove the spring guide with a 19mm
wrench. Dummy shaft system with negative spring and bumper can be
removed at this time (figure 8). Inspect rebound bumper for cracks or
distortion; replace if necessary. Secondary compression bumper,
nylon spring collar and secondary compression spring will stay in fork
leg. Inspect and clean these parts.
OPTIONAL 7" TRAVEL KIT INSTALLATION
See figure 9 for proper sequence of parts for 7" travel. Dummy shaft
system changes are: 6" travel limiter pn. P3308 is replaced by 7"
travel limiter spacer and nylon washer pn P3321 & P3322.
Compression spring changes are: 7" kit nylon spring separator is
installed on top of main spring and 7" kit spring is installed next. No
other changes are necessary.
LEFT FORK LEG (SPRING SIDE) ASSEMBLY
5.) At this point clean all parts with a clean, non-abrasive rag. A mild
grease cutting cleaner or solvent might make this an easier task.
6.) Once clean, inspect seals for tears or cracks. Next, inspect the fork
tubes for wear, nicks or scrapes. If there is noticeable play between
fork legs and fork tubes, the DU bushes located inside the upper fork
stanchion may require replacement. Consult White Brothers or your
dealer if servicing or repair is necessary.
7.) If everything is free of problems, coat all parts with a light coating
of suspension lube or other suitable, non-lithium grease. Also lube
the DU bushings that are located inside fork outer leg by dipping a
socket extension in grease and applying the grease to the DU
bushings.
8.) Install into outer fork leg (if they have been removed), oil seal,
circlip and wiper seal. With fork laid over on its side mounted in vise
(so dummy rod doesn't fall into lower fork leg), slide outer leg onto
inner leg. Be careful not to fold seal lips on oil seal and wiper seal
when sliding outer leg onto inner leg.
9.) Then install spring spacers, main spring, and upper spring seat.
Next, thread jam nut down until there is 1/2" (13mm) of exposed
thread to engage in top cap. The shaft has 9 mm flats to hold if the
jam nut is hard to thread on or off. Thread fork cap onto dummy rod
and tighten full against 9/16" nut.
10.) Thread fork cap into outer fork leg and tighten fully. Stroke fork
to check for smooth operation.
11.) Reinstall fork legs into fork crowns as instructed in Fork
Installation section.

WARRANTY
White Brothers forks are designed to enhance riding pleasure and as such are warranted to be free from defects in materials and workmanship
for a period of six months from the date of purchase. On receipt of the fork by White Brothers, if they are found to be defective, White Brothers
will determine whether to replace or repair the fork. This warranty is the sole and exclusive remedy. White Brothers shall not be liable for any
indirect, special or consequential damages. Warranty does not apply to any product that has been installed improperly or adjusted using

modifications not outlined in this manual. This warranty does not cover breakage, bending, or damage that may result from crashes, falls or
abuse. Normal wear (i.e. seals, bushings, slider finish, etc.) and wear and damage caused by lack of proper maintenance is not included. *A
